Thanks for all the advice guys. To answer all the questions here are the specs right from the blue print site. also my carb is a Holley 4150 series race carb #hly-0-9379 in the summit catalog , my fuel system consists of a 1/2 " fuel line from the tank to a holley electric fuel pump then 1/2" line to a holley mechanical pump to a regulator(set to 6psi) then to the carb. The dyno sheet said 470 horse @ 5800 and 510 lbft torque @ 4100. I've always built my own motors but time was a factor and for a $500 difference I got a warranty and when its up theres room to make more power! I planned on checking all the basic easy stuff first but thought i'd pick everybodies brains before diving in.thanks again! Pete
